...Application led June13, 192,5. SeriaIkN'o. 36,807.

My invention relates to stove construction l and particularly to sheet metal structures such as the ovens of gas ranges and the attachment of thesides or panelsthereof.

In stove construction, lit is common practice to secure the panels or sides in position permanently or by` means o-f bolts, rivets or thelikenand especially where thepanels or sides .of ovens` ,are enameled landvbecom-e burnt vor disco-lored from 'heat,or cracked,

there has been no means'for permitting convenientV removal of the defectivev parts or yvalls and renewing and replacing theysame with new and perfect parts. A Furthermore,

the fastening means render the stove unsightly in appearance.

The objectJ ofl he ypresent inventionis,

therefore, to overcome the `above objections by providing simple and novel means for securing the panels and sides in positio-n to the frame of the oven or other suitable parts, Without perforating ythese parts 0r the frame or the employment of bolts or similar fasten ing means passing through thelparts, and in,

which Ltheffastening means are concealed from View so as to provide ya strong, substan-v tial and a neat and attractive structure which greatly improves the appearance of the stove or range. y The invention further consists in certain novel combinations and arrangement'of parts l f to lbe hereinafter specified. y,

ay, of rig. 2.

In the drawingsrj, l y Fig'lis a perspective View rof a gas range having the panels or lWalls thereof vsecured yin :position in accordance with the invention. Fig.'2 is an enlarged fragmentary sectional elevationl looking atthe inside of the frame andivalls such as the oven structure, show.- ing the applicationr of V`the novel fastening means of the invention.

' employed in connection `vvith'the ovenstlruc- `ture including the rbalie oven 13l vand the broiler section 14 having doorsfl andfl.' The frame asl 12, is usually of angle metal and receives thedoorl frames thereagainstV and is adapted at the front [and rear ofthe oven' structure to .receivel Within thewebsor flangesk thereof the usual panels orfvvalls 17 of the oven which, heretofore, have been 'held 1n position by. perforating the parts and connecting the same by bolts or the like,

leaving the fastening meansexposed, or by vpermanent securing means `Which render renewal ofthe walls diiicult, if not impossible. Since some of the Walls are usually enameled,

such as the sides, it is desirable to provide i means for conveniently renewing these parts, and it is for this purpose Ythat` the present fastening means has been devised. I,

In accordance Withthe invention, the Walls 17 are provided with depressed portions 18 along theiredges to provide shoulders 19 adapted to abut the edges. of the 'l angular frame partslQ. AsshoWn, the depressed portions 18 lit `Within theflanges or sides of the frame, thus bringing the outer .facesof `the fr ame Yand panels 4or lWalls 17 substant tially 1n alignment or saidwvall's may project slightly beyond the lframein an outwarddirection. Onei ofthe side Walls 17 is provided with an inwardlyturned edge oriflange 20,

abutting theinner face lof the `other sideor flange of the frame 12and therear'panel or Wall arranged atv right angles thereto, or the inner` edge ofthe adjacent flange of the frame is provided at the inner face with a-iiange ,or strip 21 having'an inwardly offset portion22 at its edge terminating inspaced" re- .lation t0. the side Wall or depressed portion 18 there-of and providing a keyway between it and the rear flange of the frame l12; yAt

4spaced pointsthe off-set portion 22 is provid-y ed with elongated recesses or 'cutouts 2 3' to permit the insertion of'wedge-lreys `Qfbetween the offsetportions thus 'provided vand the flange 2O.'l

ings Athat `the lyzeyszazafre lconvenedy trans versely asv indicated at'Q yand have heads 26 in the formv of right kangular portionsat the large endsl thereof, which heads have theirl It will be noted'ffrom Figl 3 of the draw-V outer ledges beveled as at-27."gThese keys are inserted in the recesses 23 beneath the offset portions 22 to exert a wedging or retaining action between the same and the flange 20 to firmly secure the panels or walls in position when the wedges are moved into place. The heads 26 may serve as means for apply- -ing the wedges as well as removing the same forconvenient detachment ofV the parts in removing defect-ive panels and rep-lacing the same with perfect ones. Whether the depressed portions 21 are formed with the rear panels or separate therefrom, they may be securely attached to the inner face of the frame flange as by spot welding-at suitable points, indicated at 28. This structure is preferable since the rear panel is usually of sheet metal without an enamel coating whereas the sides are usually and preferably enameled for appearance and facility in cleaning.

The oven is usually provided with supports or ribs 29- for sup-porting trays or c shelves, and these may be provided upon a lining 30 having an inwardly offset portion 31 produced by a shoulder 32. The offset portion m-aybeprovided with Ventilating holes 33. and is further provided with a flange 34 extending in acute-angled relation to the plane of the lining to overlie the fastening means and associated parts where,- by the same are concealed from view and an unsightly appearancer avoided. This is rendered possible by providing the flange 34 with recesses 3,5 adapted' to lreceive theA heads 26 of the wedge-keys 24. The recesses areV made sufficiently wide to permit necessary movement ofthe lining to.` insure proper fit.

The linings are usually snapped into po.- sition and held by interfitting engagement with the top. and bottomv of the oven and the shelves, as is customary.` The lining also forms` an insulating air space 36 with the side 17 and may provide-an additional ventilating flue' between it and a supplement-ary wall 3,8, although the lining may be made straight instead of being depressed inwardly as clearly shown in Figs. 4 and 5 of theA drawings.

The beveled edge 27 of the head 26 of the wedges or keys 24 permit free insertion o-f the keys andy better accommodation of the lining. It will also` be apparent that by removing the lining, the keys are readily accessible and when removed from the-in seats will perm-it convenient detachment of defective or cracked sides or panels and replacement thereof by perfect parts..

Obviously, chan-ges may be made in the details lset forth without departure from the essentials, of the invention as` definedl in the claims. Y

I claim as my invention: Y

l. vIn av stove construction, a frame member, a panel having engagement with the inner face thereof, an inwardly spaced flange along the adjacent portion of the frame member and a key frictionally inserted between said flange and the panel to removably secure the latter in position.

.2. In a stove construction, an angular metal frame member, a wall having a. depressed portion fitted against one side O the frame member, an inwardly offset flange secured along the inner face of the other side of the frame member and having recesses'therein, andjveclge-keys inserted in the recesses between the flange and the depressed portion of the wall to secure the latter in position.

In a securing means for panels .of stove structures, the combination withga right angular frame member, a panel fitted against the inner face of onel flange thereof, and having its inner edge directed angularly to contact with the inner face of the .other flange, a wallsecured to the inner face vof oneV said flange andhavingy its -edgefportion offset inwardly to provide .a keyway, and a wedge-key insertedbetween said angularly directed portion of the panel and said offset portion to frictionally anchor the panel to the frame member. Y
